Learn REBOL with Real Code Examples
Updated Nov 20, 2025
Explain
REBOL is versatile for scripting, prototyping, and data exchange.
It supports domain-specific dialects for GUI, networking, and data handling.
Often used for distributed systems, lightweight applications, and custom protocols.
Core Features
Series-based data structures (strings, blocks, and binaries)
Rich networking and protocol support
REBOL dialects for specific domains (VIEW, VID, etc.)
Functions, objects, and lightweight OOP support
Interactive console and REPL environment
Basic Concepts Overview
Series: strings, blocks, and binaries
Functions: defining and calling routines
REBOL dialects for specialized tasks
Data types: integers, strings, blocks, objects
Evaluation model and series manipulation
Project Structure
scripts/ - main REBOL programs
lib/ - reusable modules or dialects
data/ - input/output files or blocks
gui/ - VIEW or VID interfaces
docs/ - documentation for scripts and dialects
Building Workflow
Write REBOL scripts (.r or .reb files)
Test interactively in the REBOL console
Use dialects for GUI, network, or file operations
Debug scripts and network communication
Deploy lightweight scripts or GUI applications
Difficulty Use Cases
Beginner: simple scripting and series manipulation
Intermediate: small GUI apps or data automation
Advanced: networking clients or servers
Expert: custom dialect development
Embedded: lightweight, portable REBOL scripts
Comparisons
Much lighter than Python or Java
More expressive for DSLs than traditional languages
Smaller ecosystem than mainstream languages
Great for scripting, less for heavy computation
Portable across platforms with minimal installation
Versioning Timeline
1997 – REBOL 1 released by Carl Sassenrath
1998 – REBOL 2 introduced with block-oriented syntax
2000s – REBOL 2/3 versions for network and GUI

Glossary
Series: sequences of values like blocks or strings
Dialect: specialized REBOL syntax for specific tasks
FUNC: function definition
VID/VIEW: GUI dialect for building interfaces
BLOCK!: primary data container in REBOL
